IMPROVEMENT IN TRUSSES.

S ec fication forming part of Letters Patent No. 176,182, dated April 18, 1876; application u'led October 22, 1875;

To all whom 1' t may concern:

Be it known that we,R. W. JOHNSON and L. L. YOUNG, of Fort Dodge, in the county of Webster and State of Iowa, have invented a new and useful Improvement in Fastenings t'or Trusses, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which Figure 1 is a perspective view, showing the fastei'iing adjusted to the rubber hemisphere A and the belt D. Fig. 2 is an end view, and

Fig. 3 is a perspective view, of the plate B, showing the projections a and a, and the teeth b b, 850.

The object of our invention is to securely fasten the rubber hemisphere A to the belt D, and still to admit of its being taken off and moved to otherparts of the beltDreadily.

In carrying out our invention we construct the metal plate 0 with two sides turned up, as shown in the drawings, and the plate G is supplied with a metal button, E. The plate O is further constructed with two slots, one in each of the two sides.

The plate B has a hole through it of the proper size to fit around the rubber hemisphere A, and is further supplied with two projections, a and a, one on each side. The

object of each is to fit into the slots in the plate 0. The plate B is further supplied on each end with the teeth b b, &c.

The operation of our invention is as follows The belt D is placed in the plate 0, and the rubber hemisphere A is adjusted to the plate B. The projections a and a on the plate B are inserted in the slots of the side pieces of the plate 0 by springing the same open to admit the projections a and a.

When the plate B is forced into place the teeth I) b, 850., are forced into the belt D, thus holding the hemisphere A firmly to the belt D.

We desire to apply our invention to a certain truss, for which Letters Patent No. 167,977 were granted September 21, A. D. 1875, to L. L. Young and John Thistle; but it may be used with any elastic belt.

What we claim as ourinvention, and desire to secure by Letters Patent, is

The combination, in a truss-fastening, of the slotted plate (3 with the toothed plate B, with its projections a a, as and for the purposes as shown and described.
